How do we find the perimeter of a composite shape?
First we find the arc length and then use the rule:
P=l*2r.
Or am I wrong? My textbook is not too clear about it.

A composite shape is just more than one shape put together.
A perimeter is just the distance around the outside.
There is no set formula. It depends on what the shapes are. :)
